ANCHOR INSERT FOR CONCRETE WORK.

Application filed January 6, 1928. Serial No. 244,863.

The main objects of this invention are to provide an anchor insert forconcrete and coacting tie members which is well adapted for use in thewalls and ceilings of buildings, the insert being very securely imbeddedin the concrete body without materially weakening the same and one withwhich ties may be quickly engaged in any desired position and the tiesare securely retained.

Objects relating to details and economies of my invention will appearfrom the description to follow. The invention is defined and pointed outin the claims.

A structure which is a preferred embodiment of my invention isillustrated in the accompanying drawing, forming a part of thisapplication, in which:

Fig. 1 is a fragmentary portion of a wall and a wall facing with myimproved anchor inserts in operative relation thereto.

Fig. 2 is a fragmentary perspective view of a concrete wall or body withone of my improved anchor channel members imbedded therein.

Fig. 3 is a fragmentary perspective view of my improved anchor wallmember.

In the drawing similar reference char acters refer to similar partsthroughout the several views.

Referring to the drawing, 1 represents aconcrete body such as a wall and2 the anchor part, such as a brick wall.

My improved anchor insert 3 is formed of sheet metal into an L or angledcross section. This is imbedded in the concrete body as the body ispoured with the edges 4 of the channel member in flush relation to theface 5 of the body.

The member 3 is of such dimensions that a substantial overhang 6 ofconcrete is secured, thereby very effectively and securely anchoring theinsert in the concrete body with a minimum of splitting or fracturingaction when stress is applied to the anchor member.

I provide a plurality of tie members 7 having arms 8 at their inner endswhich are adapted to be introduced into the channel when presentedlongitudinally to the slot or entrance thereof, as indicated in Fig. 2.

ing a channel member These tie members, when used for anchormg a facingwall, as 2, have laterally turned outer ends 9.

The tie members are a comparatively close fit in the anchoring channelso that it is qulte impossible to withdraw the same by a direct pull onthe tie member, the tie members holding securely unless withdrawn by apartially rotative movement to align the arms thereof with the slot orentrance portion of the channel.

If desired, the outer ends of the tie mem bers may be variously shapedaccording to the work for which they are intended or the part which theyare designed to anchor.

My improved anchor insert is very simple and economical and is capableof use in a great variety of relations and the ties may be quicklyinserted and adjusted to any desired position.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. An anchor for concrete work comprisof L cross section adapted to beimbedded in a concrete body with its edges flush with the face of thebody and its arm portions substantially spaced from the face of thebody, and angled tie members adapted to be introduced into said channelmember when their arms are presented longitudinally thereto andinterlocked therewith by a rotative movement within the channel member,said tie members being freely adjustable longitudinally of said channelmembers.

2. An anchor for concrete work comprising an elongated channel member ofL cross section adapted to be imbedded in a concrete body to open at thesurface of the body, and

'a tie member having a laterally projecting arm adapted to be introducedinto said channel member when the arm is presented 1ongitudinally to thechannel member and to be engaged therewith by a rotative movement of thetie member.

In Witness whereof I have hereunto set my hand.

DEWEY H. BITNEY.
